As part of your migration journey from Oracle to Amazon Aurora PostgreSQL-Compatible Edition on the Amazon Web Services (AWS) Cloud, you might encounter multiple challenges. For example, migrating code that relies on the Oracle UTL_FILE utility is always a challenge. In Oracle PL/SQL, the UTL_FILE package is used for file operations, such as read and write, in conjunction with the underlying operating system. The UTL_FILE utility works for both server and client machine systems.
Amazon Aurora PostgreSQL-Compatible is a managed database offering. Because of this, it isn't possible to access files on the database server. This pattern walks you through the integration of Amazon Simple Storage Service (Amazon S3) and Amazon Aurora PostgreSQL-Compatible to achieve a subset of UTL_FILE functionality. Using this integration, we can create and consume files without using third-party extract, transform, and load (ETL) tools or services.
